vsc trac off mean scan with c1363, does it cost a lot to fix this problem? is it safe to drive without fixing it?

It is fine to drive it means the system that helps you control the truck in an aggressive mode if off line. Btw, that alarm turns on for many reasons on my 2002 Sequoia (330,000 miles). Bumpy off roading , over heating incident, plugged in a Bluetooth code reader, and once on a high speed dip in road situation. All cleared by shutting down the truck and restarting.

2002 Sequoia here - I believe I've fixed the VSC/Trac light issue with no outside help and you can too (maybe). My Sequoia recently started intermittently giving me the VSC/Trac lights (no check engine, just VSC/Trac). Turning the car off, the lights would go away but would eventually return, maybe a drive or two. Anyway, I scanned with Toyota TechStream software (that's the dealer diagnostic software) and got a code C1363 (Booster Petal Force Circuit Fault). I saw a post online where a Toyota tech said that C1363 meant I needed a new brake booster. Before buying a new BB, I decided to check the two electrical connections to the BB. I unplugged the electrical connector to the master cylinder and the one to the brake booster. I sprayed some compressed air (from a spray can you can buy at Stapes) into both sides of the connection and then reconnected them, pressing them in place with some force. Drove the Sequoia, no codes. Scanned after 100 miles, no more C1363 code. I think the electrical connections are just old and the connections just needed some cleaning and to be pressed back in place. Hope this helps and you guys have the same result.

Hi, I had this same problem. I learned from the video, in the link below, that it is possibly a yaw sensor, which is under the cup holder/storage console. If that needs replacing, you will get those two lights coming on on the dashboard (no check engine light). https://www.youtube.com/watch?v=mxE_v9fHsRA
